Hi,running pg-jdbc 42.2.2.jre7 against | PostgreSQL 10.4 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28), 64-bit |

and using CallableStatement interface.When the application crashes after cstmt.execute(), not closing or rolling back anything the query stays active and keeps the table locked (the function, uses in/out parameters and inserts to a table).This would probably be the same if the client suddenly disconnects with a open CallableStatement which was executed but not closed, committed or rolled back.The application in question is required to use CallableStatement.I tried with settingstcp_keepalives_idle
tcp_keepalives_interval
tcp_keepalives_count |

all set to 2.Doesn't help, the query is still listed as active and the table lock is preventing other connections from doing anything for hours.Is there any solution to this kind of deadlock caused by connection being lost?What i would expect to happen: The DB recognises the connection is gone within 6 seconds and rolls back the transaction, thereby releasing the lock.Thanks in advance,Pieter Zieschang_________________________________________Modis IT Outsourcing GmbHKohlgartenstrasse 11, 04315-LeipzigAmtsgericht Düsseldorf: HRB 78227Geschäftsführer: Martin Wimmer, Andreas Bucheltwww.modis.de Diese E-Mail und alle Anhänge sind vertraulich und für den Adressaten bestimmt und können auch privilegiert oder von der Offenlegung nach geltendem Recht ausgenommen sein.
